Alternate reality:
use DateTime ( Defaults => {
parser => DateTime::Parser::Mysql,
parserargs => ...
});
my $dt = DateTime::parse($mysql_dt_string);
or
DateTime::parserargs(...);
my $dt = DateTime::parse($mysql_dt_string);
or
my $dt = DateTime::parse($mysql_dt_string, { parserargs => ... });

my $p = DateTime::Parser::Mysql->new(...);
my $f = DateTime::Formats::Mysql->new(...);

my $f = DateTime::Formats::Mysql->new(...);
my $dt = DateTime->new($mysql_dt,
{ parser => DateTime::Parser::Mysql });
print $f->as_timestamp($dt, { length => 8 });
